Re: [Cppcms-users] Booster-PCRE linking

[Artyom B. <art...@ya...>]

Is it still relevant?

What usually you do is not to specifiy explicitly the PCRE path but rather let CMake find it,
 

        -DCMAKE_INCLUDE_PATH="../../pcre-8.32.target/pub/include" \
        -DCMAKE_LIBRARY_PATH="../../pcre-8.32.target/pub/lib:zlib-1.2.7.target/pub" ..

Without ZLIB=... PCRE_LIB= etc.

Note it is also to run make install in PCRE and ZLIB - install them to a single location with all correct files and libraries and THAN use rater
than pointing to source directories.

Also it seems that you are mixing shared and static libraries (../../pcre-8.32.target/pub/lib/libpcre.so")
