我正在构建lua作为外部项目,我想使用我自己的CMakeLists.txt而不是捆绑的Makefile。这就是我在我的主要CMakeLists.txt中所拥有的:
include(ExternalProject)
set(lua_RELEASE 5.1.4)
ExternalProject_Add(
lua-${lua_RELEASE}
URL http://www.lua.org/ftp/lua-${lua_RELEASE}.tar.gz
DOWNLOAD_DIR ${CMAKE_CURRENT_BINARY_DIR}/download/lua-${lua_RELEASE}
SOURCE_DIR ${CMAKE_CURRENT_SOURCE_DIR}/thirdparty/lua/lua-${lua_RELEASE}
BINARY_DIR ${CMAKE_CURRENT_BINARY_DIR}/build/lua-${lua_RELEASE}
UPDATE_COMMAND ""
PATCH_COMMAND ""
INSTALL_COMMAND ""
)
要使BUILD步骤起作用,SOURCE_DIR中必须有一个CMakeLists.txt。我现在在SOURCE_DIR中有这个CMakeLists.txt:
cmake_minimum_required(VERSION 2.8)
project(lua)
set(lua_library
lapi.c lcode.c ldebug.c ldo.c ldump.c lfunc.c lgc.c llex.c
lmem.c lobject.c lopcodes.c lparser.c lstate.c lstring.c
ltable.c ltm.c lundump.c lvm.c lzio.c
lauxlib.c lbaselib.c ldblib.c liolib.c lmathlib.c loslib.c
ltablib.c lstrlib.c loadlib.c linit.c
)
foreach(s ${lua_library})
set(lua_LIBRARY ${lua_LIBRARY} src/${s})
endforeach()
add_definitions(-DLUA_ANSI=1)
add_library(lua STATIC ${lua_LIBRARY})
这有效,但我不满意让lua源文件混乱我的版本控制的CMakeLists.txt。
有没有办法为SOURCE_DIR中不的构建步骤指定自定义CMakeLists.txt?
答案 0 :(得分:16)
我自己想通了。我现在将其用作PATCH_COMMAND
:
PATCH_COMMAND ${CMAKE_COMMAND} -E copy
"${CMAKE_CURRENT_SOURCE_DIR}/thirdparty/lua/CMakeLists.txt" <SOURCE_DIR>/CMakeLists.txt
这允许我在thirdparty/lua
中拥有自定义的CMakeLists.txt,并将上游包下载到thirdparty/lua/lua-${lua_RELEASE}
。完美!
