mingw+cmake+QT的GeographicLib库

# This CMakeLists.txt is invoked in two different ways # (1) With "add_subdirectory (examples)" from GeographicLib's top-level # CMakeLists.txt. This mode of invocation is flagged by the variable # # CALLED_FROM_TOPLEVEL # # In this case, the only action taken is to install the examples and # this CMakeLists.txt in ${EXAMPLEDIR}. # (2) As an independent invocation of # # cmake -S -B # # In this case, find_package (GeographicLib) is called and the examples # are compiled. This mode of invocation is triggered by the # exampleprograms target in the top-level CMakeLists.txt.
