Subject: CMakeLists.txt: fix version in zlib.pc when building statically
X-Git-Tag: 2.1.0-beta1~234
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=6038b6443257e725b3aa3b0bbeeb8ee01474a565;p=thirdparty%2Fzlib-ng.git

CMakeLists.txt: fix version in zlib.pc when building statically

When building statically (i.e. with BUILD_SHARED_LIBS=OFF),
ZLIB_FULL_VERSION is not set resulting in an empty version in zlib.pc
and the following build failure with transmission:

checking for ZLIB... configure: error: Package requirements (zlib >= 1.2.3) were not met:

Package dependency requirement 'zlib >= 1.2.3' could not be satisfied.
Package 'zlib' has version '', required version is '>= 1.2.3'

Fixes:
