I would like to have some clarification about module and include
effective search order:
I am in the following situation:
I use (configure) a project that is overriding some CMake standard Find
modules by doing in his main CMakeLists.txt file:
SET(CMAKE_MODULE_PATH "<ProjectModuleFolder>;${CMAKE_MODULE_PATH}")
I would like to being able to override, at configure time the project
modules with mine.
Doing:
cmake -DCMAKE_MODULE_PATH:PATH=<myModuleFolder>
does not work (my files are searched AFTER projects files)
Is it safe to just change project CMakeLists.txt to
SET(CMAKE_MODULE_PATH "${CMAKE_MODULE_PATH};<ProjectModuleFolder>")
Or, on older CMake version this could result in getting standard CMake
modules found first?
Otherwise I have to propose a safer patch like:
set(USER_MODULE_PATH "" CACHE PATH "set this to define a folder for
module override")
if(USER_MODULE_PATH)
set(CMAKE_MODULE_PATH
"${USER_MODULE_PATH};<ProjectModuleFolder>;${CMAKE_MODULE_PATH}")
else(USER_MODULE_PATH)
set(CMAKE_MODULE_PATH "<ProjectModuleFolder>;${CMAKE_MODULE_PATH}")
endif(USER_MODULE_PATH)
Thanks in advance
Luigi
