The problem is the line:
if(${_var} MATCHES "^WITH_LIB_([AZaz]+)$")
cmake_print_variables(CMAKE_MATCH_0)
doesn't print me any output ...

Hi everyone,
i try to create a build system where you can decide which libraries
you want to use with variables like "WITH_LIB_GLFW" for example. every
lib variable has other variables like WITH_LIB_GLFW_INC_PATH,
WITH_LIB_GLFW_LIB_PATH, etc. so i can decide with cmake what libraries
i'm going to use for the final executable.
Now my problem is that i'm relative new to cmake and i'm learning
c++11 in the meantime and are coding on a project so i don't have to
much time for cmake (but it's a realy important part).
Here is the code:
cmake_minimum_required(VERSION 3.14 FATAL_ERROR)
include(CMakePrintHelpers)
set(WITH_LIB_GLAD "Support the GLAD library" 1)
set(WITH_LIB_GLFW "Support for the GLFW library" 1)
macro(bsAddLibrary lib)
# get all WITH_LIB varables
get_cmake_property(_variables VARIABLES)
foreach(_var ${_variables})
# cmake_print_variables(${_var})
if(${_var} MATCHES "^WITH_LIB_[AZaz]+$" _lib)
cmake_print_variables(${_lib})
endif()
endforeach()
endmacro()
bsAddLibrary(WITH_LIB_GLAD) # Adds WITH_LIB_GLAD_INC_PATH and the other
variables to a list for the main application that holds all inc path, compiler
flags etc.
