Incorporate support for *.in files:

I think we may want to include the generation of shared libraries.
In that case the test files should be excluded:

list(REMOVE_ITEM speexdsp_SOURCES
    ${CMAKE_SOURCE_DIR}/libspeexdsp/testdenoise.c
    ${CMAKE_SOURCE_DIR}/libspeexdsp/testecho.c
    ${CMAKE_SOURCE_DIR}/libspeexdsp/testjitter.c
    ${CMAKE_SOURCE_DIR}/libspeexdsp/testresample.c
    ${CMAKE_SOURCE_DIR}/libspeexdsp/testresample2.c
)

add_library(speexdsp ${SPEEXDSP_SOURCES})

# Installation rules
install(TARGETS speexdsp
EXPORT speexdspConfig
RUNTIME DESTINATION bin
LIBRARY DESTINATION lib
ARCHIVE DESTINATION lib
)
install(DIRECTORY include/ DESTINATION include)
