+Subject: [PATCH] pkg-config: fix gtest.pc/gmock.pc library names for the debug
+ build
+
+In case CMAKE_BUILD_TYPE is set to Debug the gtest library is
+name libgtestd.a but the link command returned from gtest.pc is
+'-lgtest' (without the debug d) and so the linking of dependent
+packages fails (see [1] for a buildroot failure example).
+
+Enhance the gtest.pc ang gmock.pc generation to honour the debug 'd'.
