You can specify linker flags in <a href="http://www.cmake.org/cmake/help/v2.8.8/cmake.html#command%3atarget_link_libraries" rel="noreferrer">target_link_libraries</a>.

blocks|key|893842|text|这有点取决于你想要什么：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|893843|A)如果您想指定要链接到哪些库，可以使用find_library查找库，然后使用link_directories和target_link_libraries。|offset|length|893844|当然，写一个好的find_package脚本通常是值得的，它很好地添加了具有正确位置的add_library(+YourLib+IMPORTED+)的“导入”库，以及平台/构建特定的前缀和后缀。然后，您可以简单地引用'YourLib‘并使用target_link_libraries。|893845|B)如果您希望指定特定的链接器标志，例如‘-mthread’或'-Wl，--export-all-symbols‘，您可以使用CMAKE_EXE_LINKER_FLAGS。对于模块、共享库或静态库，还有两个类似但没有文档记录的标志：|893846|CMAKE_MODULE_LINKER_FLAGS

It depends a bit on what you want: 

A) If you want to specify which libraries to link to, you can use <a href="http://www.cmake.org/cmake/help/v2.8.8/cmake.html#command:find_library" rel="noreferrer">find_library</a> to find libs and then use <a href="http://www.cmake.org/cmake/help/v2.8.8/cmake.html#command:link_directories" rel="noreferrer">link_directories</a> and <a href="http://www.cmake.org/cmake/help/v2.8.8/cmake.html#command:target_link_libraries" rel="noreferrer">target_link_libraries</a> to. 

Of course, it is often worth the effort to write a good <a href="http://www.cmake.org/cmake/help/v2.8.8/cmake.html#command:find_package" rel="noreferrer">find_package</a> script, which nicely adds "imported" libraries with <a href="http://www.cmake.org/cmake/help/v2.8.8/cmake.html#command:add_library" rel="noreferrer">add_library( YourLib IMPORTED )</a> with correct locations, and platform/build specific pre- and suffixes. You can then simply refer to 'YourLib' and use target_link_libraries.

B) If you wish to specify particular linker-flags, e.g. '-mthreads' or '-Wl,--export-all-symbols' with MinGW-GCC, you can use <a href="http://www.cmake.org/cmake/help/v2.8.8/cmake.html#variable:CMAKE_EXE_LINKER_FLAGS" rel="noreferrer">CMAKE_EXE_LINKER_FLAGS</a>. There are also two similar but undocumented flags for modules, shared or static libraries:

<pre><code>CMAKE_MODULE_LINKER_FLAGS
CMAKE_SHARED_LINKER_FLAGS
CMAKE_STATIC_LINKER_FLAGS
</code></pre>

For linking against libraries see <a href="https://stackoverflow.com/a/6088646/3162383">Andre's answer</a>.

For linker flags - the following 4 CMake variables:

<pre><code>CMAKE_EXE_LINKER_FLAGS
CMAKE_MODULE_LINKER_FLAGS
CMAKE_SHARED_LINKER_FLAGS
CMAKE_STATIC_LINKER_FLAGS
</code></pre>

can be easily manipulated for different configs (debug, release...) with the <a href="https://github.com/onqtam/ucm#ucm_add_linker_flags" rel="nofollow noreferrer">ucm_add_linker_flags</a> macro of <a href="https://github.com/onqtam/ucm" rel="nofollow noreferrer">ucm</a>

I set the CFLAGS in CMake by CMAKE_C_FLAGS.
Is something like this to set LDFLAGS?

How to set the LDFLAGS in CMakeLists.txt?

我通过CMAKE_C_FLAGS在CMake中设置了CFLAGS。像这样设置LDFLAGS吗？
