CMake:设置CMAKE_CXX_FLAGS

Muduos的CMakeLists.txt中,MAKE_CXX_FLAGS设置较为清晰明了,因此一直在项目中沿用.

 1 set(CXX_FLAGS
 2         -g
 3         # -DVALGRIND
 4         -DCHECK_PTHREAD_RETURN_VALUE
 5         -D_FILE_OFFSET_BITS=64
 6         -Wall
 7         -Wextra
 8         -Werror
 9         -Wconversion
10         -Wno-unused-parameter
11         -Wold-style-cast
12         -Woverloaded-virtual
13         -Wpointer-arith
14         -Wshadow
15         -Wwrite-strings
16         -march=native
17         # -MMD
18         -rdynamic
19         )
20 
21 string(TOUPPER ${CMAKE_BUILD_TYPE} BUILD_TYPE)
22 CMAKE_CXX_FLAGS
23 #string(REPLACE ";" " " CMAKE_CXX_FLAGS "${CXX_FLAGS}")
24 string(REPLACE ";" " " CMAKE_CXX_FLAGS "${CXX_FLAGS}")

需要注意的是,以上编译参数均是针对gcc.

如果使用clang编译器,需要自行进行替换.
