# CPack Example: User-selectable Installation Components
#
# In this example, we have a simple library (mylib) with an example
# application (mylibapp). We create a binary installer that allows
# users to select which pieces will be installed: the example
# application, the library binaries, and/or the header file.

# Create the mylib library
add_library(mylib mylib.cpp)
# Create the mylibapp application

# On Linux, enable using an absolute install path to verify that
# CMAKE_INSTALL_PREFIX and CPACK_SET_DESTDIR interact properly.
#
# But only use absolute paths if not targeting an NSIS installer
# as indicated by CPACK_BINARY_NSIS. (If we allow this, the test
# fails on Linux machines with makensis installed when we are not
# cross-compiling...)
