How to define a list of files matching a pattern in CMake?

Question

How can I define a variable in CMake containing a list of files that match a pattern? For instance, test_*.cpp?

And how can I define a variable containing a list of files that DON'T match a pattern? For instance, test_*.cpp should match all files EXCEPT those matched above.

Answer 1

For matching the source files of a particular pattern , you can use globbing pattern.

file(GLOB_RECURSE TEST_FILES
  "${PROJECT_SOURCE_DIR}/src/test_*.cpp"
)

I'm not sure of how to exclude those specific files, maybe excluding them from the list of all the files work , like this

file(GLOB_RECURSE SRC_FILES
  "${PROJECT_SOURCE_DIR}/src/*.cpp"
)
list(REMOVE_ITEM ${SRC_FILES} ${TEST_FILES})

I was referring to list REMOVE_ITEM from this source http://www.cmake.org/cmake/help/v3.0/command/list.html
