This macro recursively collects the files from a project directory and caches the list for future use. Tailor the extensions that are included in the list according to your needs.
# add extra sources to the defined project
MACRO ( GatherProjectFiles ProjectName ProjectDir ProjectSources )
#look for the cache file
SET ( FoundCacheFile "FoundCacheFile-NOTFOUND" )
FIND_FILE ( FoundCacheFile ${ProjectName}Sources.cmake PATHS ${CMAKE_CURRENT_BINARY_DIR} NO_DEFAULT_PATH NO_CMAKE_ENVIRONMENT_PATH NO_CMAKE_PATH NO_SYSTEM_ENVIRONMENT_PATH NO_CMAKE_SYSTEM_PATH)
IF ( FoundCacheFile )
# read cached file list
MESSAGE ( STATUS " Found cache file ${FoundCacheFile}" )
INCLUDE ( ${CMAKE_CURRENT_BINARY_DIR}/${ProjectName}Sources.cmake )
ELSE ( FoundCacheFile )
# get the file lists
SET ( Dir ${CMAKE_HOME_DIRECTORY}/${ProjectDir} )
# add your other extensions here (this could be probably done nicer)
FILE ( GLOB_RECURSE DirSources ${Dir}/*.c ${Dir}/*.cpp ${Dir}/*.h ${Dir}/*.inl ${Dir}/*.rc ${Dir}/*.ico )
# write cached file list

SET ( "${ProjectSources}" ${DirSources} )
ENDMACRO ( GatherProjectFiles )The template file (located in CMAKE_HOME_DIRECTORY\CMake\SourceFilesTemplate.cmake.in) looks like this:
# Cache source files
# All sources
SET ( DirSources @DirSourcesAsString@ )A typical use for this macro would be:
GatherProjectFiles ( MyLib src/MyLib MyLibSources )
