Based on the thread "cmake variable scope, add_subdirectory", the CMake set command will set the variable in the current scope only, unless the
PARENT_SCOPE parameter is specified.
Recently when I was looking at the project command, per CMake doc, variables
<PROJECT-NAME>_BINARY_DIR will be set. But it didn't mention what is the scope of these variables. Can these variable be used in other subdirectory? For example:
| |- CMakeLists.txt // add_subdirectory(proj1); add_subdirectory(proj2)
| |- proj1
| | |- CMakeLists.txt // project(proj1)
| |- proj2
| | |- CMakeLists.txt // Does this have access to proj1_SOURCE_DIR or
What about variables for other command like
Find_Package? What is the scope of the
<Module>_FOUND variable? Thanks!
