Hello, I am a new user of cmake and I am running version 2.6-patch 4 on Linux.
I am setting up a simple project to learn cmake and most everything has worked
just as expected except for my attempts to define where an output library
target is to be created. Here is part of the CMakeLists.txt
project(ZLIB C)
SET(CMAKE_INSTALL_PREFIX ${PROJECT_BINARY_DIR}/install)
SET(CMAKE_BUILD_TYPE Release)
set(CMAKE_C_COMPILER gcc)
add_definitions(-O3)
set(BUILD_SHARED_LIBS ON)
cmake_minimum_required(VERSION 2.6)
set(ZLIB_PUBLIC_HDRS
zconf.h
zlib.h
)
set(ZLIB_PRIVATE_HDRS
crc32.h
deflate.h
inffast.h
inffixed.h
inflate.h
inftrees.h
trees.h
zutil.h
)
set(ZLIB_SRCS
adler32.c
compress.c
crc32.c
deflate.c
inflate.c
infback.c
inftrees.c
inffast.c
gzio.c
trees.c
uncompr.c
zutil.c
)
set(ZLIB_TEST_SRCS
example.c
)
set(ZLIB_MAN_SRCS
zlib.3
)
add_library(z ${ZLIB_SRCS} ${ZLIB_PUBLIC_HDRS} ${ZLIB_PRIVATE_HDRS})
set_target_properties(z PROPERTIES DEFINE_SYMBOL ZLIB_DLL)
set(LIBRARY_OUTPUT_DIRECTORY ${PROJECT_BINARY_DIR}/lib)
add_executable(example ${ZLIB_TEST_SRCS})
set(RUNTIME_OUTPUT_DIRECTORY ${PROJECT_BINARY_DIR}/bin)
add_dependencies(example z)
target_link_libraries(example z)
install(TARGETS z DESTINATION lib )
install(FILES ${ZLIB_PUBLIC_HDRS} DESTINATION include)
install(TARGETS example DESTINATION bin)
install(FILES ${ZLIB_MAN_SRCS} DESTINATION share/man/man3)
I have tried many variations of setting the location for the target z to be
created (and the executable "example"), both the new style as shown above and
the old style (LIBRARY_OUTPUT_PATH), using variables as above and using
absolute paths and nothing works. libz.so is always dropped directly into my
build directory.
Interesting, if I hand edit the cache file and add the variable
CMAKE_LIBRARY_OUTPUT_DIRECTORY to change the library creation location it
works: why does my cmake configuration not respect the above commands and write
this into the cache file automatically?
Thanks,
--Randy
