# 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 (a CPack Generator)
# which supports CPack components.
#
# Depending on the CPack generator and on some CPACK_xxx var values
# the generator may produce a single (NSIS, PackageMaker)
# or several package files (Archive Generators, RPM, DEB)
