| # The library dependency data is contained in the file | ||
| # LLVMLibDeps.cmake on this directory. It is automatically generated | ||
| # by tools/llvm-config/CMakeLists.txt when the build comprises all the | ||
| # targets and we are on a environment Posix enough to build the | ||
| # llvm-config script. This, in practice, just excludes MSVC. | ||
|
|
||
| # When you remove or rename a library from the build, be sure to | ||
| # remove its file from lib/ as well, or the GenLibDeps.pl script will | ||
| # include it on its analysis! | ||
