C++ CMake无法生成安全链接器搜索路径-yocto 2.4
我有两个yocto软件包，可以在yocto 2.0.2上使用gcc 5.4、cmake 3.6.1成功编译，但我在yocto 2.4上面临以下问题：gcc 6.3、cmake 3.6.1 经过一些研究，我发现yocto改变了sysroot结构（每个包的sysroot，而不是一个普通的sysroot）。 错误如下所示：C++ CMake无法生成安全链接器搜索路径-yocto 2.4,c++,gcc,cmake,linker,yocto,C++,Gcc,Cmake,Linker,Yocto,我有两个yocto软件包，可以在yocto 2.0.2上使用gcc 5.4、cmake 3.6.1成功编译，但我在yocto 2.4上面临以下问题：gcc 6.3、cmake 3.6.1 经过一些研究，我发现yocto改变了sysroot结构（每个包的sysroot，而不是一个普通的sysroot）。 错误如下所示： CMake Warning at src/mytest/CMakeLists.txt:71 (add_executable): Cannot generate a safe l
CMake Warning at src/mytest/CMakeLists.txt:71 (add_executable):
Cannot generate a safe linker search path for target mytest because
files in some directories may conflict with libraries in implicit
directories:
link library [libpthread.so] in /local/build2/tmp/work/corei7-64-poky-linux/mytest/recipe-sysroot/usr/lib may be hidden by files in:
/local/build2/tmp/work/corei7-64-poky-linux/mylib/recipe-sysroot/usr/lib
Some of these libraries may not be found correctly.

)
有没有办法避免这种重复？或者从cmake生成的文件中删除完整路径 您能否显示mylib的
target\u link\u libraries（）pthread
