Hi Micha,
Thanks very much I tried that .. I added it to the application
directory cmakelists.txt file . Same issue .. It's already in the top
level cmake file which looks like this ..
project(CATSMAT)
cmake_minimum_required(VERSION 3.6.3)
if (APPLE)
set(CMAKE_C++_FLAGS -mmacosx-version-min=10.4)
endif (APPLE)
include_directories("catsmat/libIMUSANT")
add_subdirectory (catsmat/googletest-master/googletest)
add_subdirectory (catsmat/libMusicXMLv3/libmusicxml-3.00-src/cmake)
add_subdirectory (catsmat/libIMUSANT/cmake)
add_subdirectory (catsmat/libIMUSANT_Tests/cmake)
add_subdirectory (catsmat/catsmat/cmake)
set(CMAKE_CXX_STANDARD 14)
