[CMake] General question about variable scope.

[Steven Truppe]

Hi everyone,


i've the following code:

macro(bsBuildLibExamples lib)
	# get all examples
	get_cmake_property(_vars VARIABLES)
	foreach(_var ${_vars})
	    string(TOUPPER ${lib} lib_upper)
	    set(WITH_LIB_${lib_upper}_EXAMPLES "")
	    if(_var MATCHES "^WITH_LIB_${lib_upper}_EXAMPLE_([A-Za-z]+)$")
		message(STATUS "Example found: ${CMAKE_MATCH_1}")
		list(APPEND ${WITH_LIB_${lib_upper}_EXAMPLES} ${CMAKE_MATCH_1})
              endif()
	endforeach()

     message(STATUS "Glad examples: ${WITH_LIB_GLAD_EXAMPLES}")
     message(STATUS "GLFW examples: ${WITH_LIB_GLFW_EXAMPLES}")

endmacro()


The problem is that ${WITH_LIB_${lib_upper}_EXAMPLES} is not available
anymore after the foreach, i was not able to find something in the docs
about this, i hope someone here can help me out.


best regrads!
