Install fails to link (to zlib?)

[Phrogz]

At the end of my build:

[ 47%] Linking CXX executable bin/uscxml-browser
lib/libuscxml.so.2.0.0: undefined reference to `inflateInit2_'

Is there a specific version of zlib that I need to install first?

Same problem building ee0a17cc63316edd83388a2f8f93b48cdcc6913c on Ubuntu 18.04 with zlib v1.2.11. Any clue? Thanks, pz

Hi, I've got the same error on Ubuntu 20.

Solution:

if (CMAKE_CXX_COMPILER_ID STREQUAL "GNU")
	target_link_libraries(uscxml-browser uscxml "-lz")
else()
	target_link_libraries(uscxml-browser uscxml)
endif()
