[CMake] Re: dependency error

[Marc Paulescu]

Hello,
Because I received no reply (maybe because of the attachment) I will
post the CMakeLists contents here :

#======================================================

project(test)

if (WIN32)
    add_definitions(-D_CRT_SECURE_NO_DEPRECATE)
    add_definitions(-D_CRT_NONSTDC_NO_DEPRECATE)

        set(EXECUTABLE_OUTPUT_PATH    ${PROJECT_BINARY_DIR})
        set(LIBRARY_OUTPUT_PATH        ${PROJECT_BINARY_DIR})
    else (CMAKE_CONFIGURATION_TYPES)
        set(EXECUTABLE_OUTPUT_PATH    ${PROJECT_BINARY_DIR}/bin)
        set(LIBRARY_OUTPUT_PATH        ${PROJECT_BINARY_DIR}/bin)
    endif (CMAKE_CONFIGURATION_TYPES)
else (WIN32)

Thank you.
