-Subject: [PATCH] cmcurl: link librt
-
-When cmake is linked against LibreSSL, there might be an indirect
-dependency on librt on certain systems if LibreSSL's libcrypto uses
-clock_gettime() from librt:
-
- [ 28%] Linking C executable LIBCURL
- .../lib/libcrypto.a(getentropy_linux.o): In function `getentropy_fallback':
- getentropy_linux.c:(.text+0x16d): undefined reference to `clock_gettime'
- getentropy_linux.c:(.text+0x412): undefined reference to `clock_gettime'
- collect2: error: ld returned 1 exit status
- make[5]: *** [Utilities/cmcurl/LIBCURL] Error 1
-
-Modify the cmcurl CMakeLists.txt to check for clock_gettime() in librt
-and unconditionally link the rt library when the symbol is found.
