-Subject: [PATCH] CMakeLists.txt: fix PACKAGE_VERSION substitution in .pc file
-
-Before the change project built using `cmake` had Version field empty:
-
-    Version:
-
-After the change version is set as expected:
-
-    Version: 2.1.0
-
-Noticed as as a build failure of `echant-2.6.4` which failed to find the
-package using `pkg-config --exists --print-errors "UnitTest++ >= 1.6"`
-expression.
