### example CMakeLists.txt to develop C++ programs using OpenMS

## list all your executables here (a corresponding .cpp file should exist, e.g. Main.cpp)
set(my_executables
Main
)
## list all classes here, which are required by your executables
## (all these classes will be linked into a library)
set(my_sources
ExampleLibraryFile.cpp
)
## find OpenMS configuration and register target "OpenMS" (our library)
find_package(OpenMS)
## if the above fails you can try calling cmake with -D OpenMS_DIR=/path/to/OpenMS/
## or modify the find_package() call accordingly
## find_package(OpenMS PATHS "</path/to/OpenMS//")

## include directories for OpenMS headers (and contrib)
# Note: If you want to link against a specific library contained
# in the OpenMS package you should also list the
# corresponding include variable here, e.g.,
# OpenMS_GUI -> ${OpenMS_GUI_INCLUDE_DIRECTORIES}

## append precompiler macros and compiler flags specific to OpenMS
## Warning: this could be harmful to your project. Check this if problems occur.
## Also, use this to add your own compiler flags, e.g. for OpenMP support.
## e.g. for Visual Studio use /openmp
