ADD_CUSTOM_COMMAND(
OUTPUT ${CMAKE_CURRENT_BINARY_DIR}/copy.h
COMMAND cp ${CMAKE_CURRENT_SOURCE_DIR}/a.h
${CMAKE_CURRENT_BINARY_DIR}/copy.h
DEPENDS ${CMAKE_CURRENT_SOURCE_DIR}/a.h
)
INCLUDE_DIRECTORIES(
${CMAKE_CURRENT_BINARY_DIR} # for copy.h
${CMAKE_CURRENT_SOURCE_DIR} # becasuse copy.h needs b.h
)
ADD_LIBRARY(test
a.cpp
${CMAKE_CURRENT_BINARY_DIR}/copy.h
a.h
)
