$ pkgconf --cflags crengine-ng
Package zlib was not found in the pkg-config search path.
Perhaps you should add the directory containing `zlib.pc'
to the PKG_CONFIG_PATH environment variable
Package 'zlib', required by 'crengine-ng', not found
Package 'libpng', required by 'crengine-ng', not found
Package 'freetype2', required by 'crengine-ng', not found
Package 'harfbuzz', required by 'crengine-ng', not found
Package 'fribidi', required by 'crengine-ng', not found

Package 'libzstd', required by 'crengine-ng', not found
Package 'libutf8proc', required by 'crengine-ng', not found
Package 'fontconfig', required by 'crengine-ng', not found

Due to:
Requires.private: zlib, libpng, libjpeg, freetype2 >= 2.10.0, harfbuzz >= 2.6.0, fribidi >= 1.0.0, libunibreak >= 4.0, libzstd >= 1.4.0, libutf8proc, fontconfig >= 2.11.0


There are 2 options:
1. add the -dev packages (that are already in the build dependencies)
   to the Depends of libcrengine-ng-dev, or
2. drop Requires.private from crengine/crengine-ng.pc.cmake
