and build fails with `cannot find -lxo_bar`.
Possible causes:
1. missing cmake export for a dependency of `xo_foo`.
Check `xo_foo/cmake/xo_fooConfig.cmake.in`:
If `xo_foo` depends on `xo_bar`, then cmake export
needs to have `find_dependency(xo_bar)`

# XO cmake modules
Collects cmake macros to be shared across XO projects (e.g. indentlog, reflect, kalman, ..)
## Features
- support for both manyrepo and monorepo projects
- support for generating cmake `xxxConfig.cmake` files, so cmake `find_package()` works reliably
- support for header-only libraries
- support for pybind11 libraries
- documentation generation using doxygen + breathe + sphinx
- code coverage using ccov + lcov
## Getting Started
### copy repo
```
$ git clone https://github.com:rconybea/xo-cmake.git
```
### configure + install
```
$ cd xo-cmake
$ cmake -DCMAKE_INSTALL_PREFIX=/usr/local -B .build -S . # ..or desired prefix
$ cmake --install .build
```
## use from a cmake project
In some project `foo`:
```
$ cd foo
$ mkdir cmake
$ cp $PREFIX/share/xo-macros/xo-bootstrap-macros.cmake cmake/
```
`xo-bootstrap-macros-cmake` has two vital jobs:
1. set `XO_CMAKE_CONFIG_EXECUTABLE` (locate `xo-cmake-config`)
2. set `CMAKE_MODULE_PATH` (obtained from `xo-cmake-config --cmake-module-path`)
then in `foo/CMakeLists.txt`:
```
include(cmake/xo-bootstrap-macros.cmake)
xo_cxx_toplevel_options3()
```
Now as long as `$PREFIX/bin` is in `PATH`:
```
$ cd mybuild
$ cmake path/to/foo/source
```
### or set `XO_CMAKE_CONFIG_EXECUTABLE` and `CMAKE_MODULE_PATH`
In some project `foo`:
```
$ cd mybuild
$ cmake -DXO_CMAKE_CONFIG_EXECUTABLE=xo-cmake-config -DCMAKE_MODULE_PATH=$(xo-cmake-config --cmake-module-path) path/to/foo/source
```

# USAGE: To enable any code coverage instrumentation/targets, the single CMake
# option of `CODE_COVERAGE` needs to be set to 'ON', either by GUI, ccmake, or
# on the command line.
#
# From this point, there are two primary methods for adding instrumentation to
# targets:
#
# 1 - A blanket instrumentation by calling `add_code_coverage()`, where
# all targets in that directory and all subdirectories are automatically
# instrumented.
#
# 2 - Per-target instrumentation by calling
# `target_code_coverage(<TARGET_NAME>)`, where the target is given and thus only
# that target is instrumented. This applies to both libraries and executables.
#
# To add coverage targets, such as calling `make ccov` to generate the actual
# coverage information for perusal or consumption, call
# `target_code_coverage(<TARGET_NAME>)` on an *executable* target.
#
# Example 1: All targets instrumented
#
# In this case, the coverage information reported will will be that of the
# `theLib` library target and `theExe` executable.
#
# 1a: Via global command
#
# ~~~
# add_code_coverage() # Adds instrumentation to all targets
#
# add_library(theLib lib.cpp)
#
# add_executable(theExe main.cpp)
# target_link_libraries(theExe PRIVATE theLib)
# target_code_coverage(theExe) # As an executable target, adds the 'ccov-theExe' target
# # (instrumentation already added via global anyways)
# # for generating code coverage reports.
# ~~~
#
# 1b: Via target commands
#
# ~~~
# add_library(theLib lib.cpp)
# target_code_coverage(theLib) # As a library target, adds coverage instrumentation but no targets.
#
# add_executable(theExe main.cpp)
# target_link_libraries(theExe PRIVATE theLib)
# target_code_coverage(theExe) # As an executable target, adds the 'ccov-theExe' target and instrumentation for generating code coverage reports.
# ~~~
#
# Example 2: Target instrumented, but with regex pattern of files to be excluded
# from report
#
# ~~~
# add_executable(theExe main.cpp non_covered.cpp)
# target_code_coverage(theExe EXCLUDE non_covered.cpp test/*) # As an executable target, the reports will exclude the non-covered.cpp file, and any files in a test/ folder.
# ~~~
#
# Example 3: Target added to the 'ccov' and 'ccov-all' targets
#
# ~~~
# add_code_coverage_all_targets(EXCLUDE test/*) # Adds the 'ccov-all' target set and sets it to exclude all files in test/ folders.
#
# add_executable(theExe main.cpp non_covered.cpp)
# target_code_coverage(theExe AUTO ALL EXCLUDE non_covered.cpp test/*) # As an executable target, adds to the 'ccov' and ccov-all' targets, and the reports will exclude the non-covered.cpp file, and any files in a test/ folder.

# Adds code coverage instrumentation to a library, or instrumentation/targets

# ~~~
# EXECUTABLE ADDED TARGETS:
# GCOV/LCOV:
# ccov : Generates HTML code coverage report for every target added with 'AUTO' parameter.
# ccov-${TARGET_NAME} : Generates HTML code coverage report for the associated named target.
# ccov-all : Generates HTML code coverage report, merging every target added with 'ALL' parameter into a single detailed report.
#
# LLVM-COV:
# ccov : Generates HTML code coverage report for every target added with 'AUTO' parameter.
# ccov-report : Generates HTML code coverage report for every target added with 'AUTO' parameter.
# ccov-${TARGET_NAME} : Generates HTML code coverage report.
# ccov-report-${TARGET_NAME} : Prints to command line summary per-file coverage information.
# ccov-export-${TARGET_NAME} : Exports the coverage report to a JSON file.
# ccov-show-${TARGET_NAME} : Prints to command line detailed per-line coverage information.
# ccov-all : Generates HTML code coverage report, merging every target added with 'ALL' parameter into a single detailed report.
# ccov-all-report : Prints summary per-file coverage information for every target added with ALL' parameter to the command line.
# ccov-all-export : Exports the coverage report to a JSON file.
#
# Required:
# TARGET_NAME - Name of the target to generate code coverage for.
# Optional:
# PUBLIC - Sets the visibility for added compile options to targets to PUBLIC instead of the default of PRIVATE.
# INTERFACE - Sets the visibility for added compile options to targets to INTERFACE instead of the default of PRIVATE.
# PLAIN - Do not set any target visibility (backward compatibility with old cmake projects)
# AUTO - Adds the target to the 'ccov' target so that it can be run in a batch with others easily. Effective on executable targets.
# ALL - Adds the target to the 'ccov-all' and 'ccov-all-report' targets, which merge several executable targets coverage data to a single report. Effective on executable targets.
# EXTERNAL - For GCC's lcov, allows the profiling of 'external' files from the processing directory
# COVERAGE_TARGET_NAME - For executables ONLY, changes the outgoing target name so instead of `ccov-${TARGET_NAME}` it becomes `ccov-${COVERAGE_TARGET_NAME}`.
# EXCLUDE <PATTERNS> - Excludes files of the patterns provided from coverage. Note that GCC/lcov excludes by glob pattern, and clang/LLVM excludes via regex! **These do not copy to the 'all' targets.**
# OBJECTS <TARGETS> - For executables ONLY, if the provided targets are shared libraries, adds coverage information to the output
# ARGS <ARGUMENTS> - For executables ONLY, appends the given arguments to the associated ccov-* executable call
