make distclean ./configure make Solution : The dynamic linker cannot find your custom zlib. Update the linker cache:

gcc -I/usr/local/zlib-1.2.13/include -L/usr/local/zlib-1.2.13/lib myapp.c -lz -o myapp # Tell CMake where to find this specific zlib set(ZLIB_ROOT "/usr/local/zlib-1.2.13") find_package(ZLIB REQUIRED) target_link_libraries(your_target PRIVATE ZLIB::ZLIB) For Python (Using ctypes or C extensions) Python's zlib module is typically built against the system zlib. To force a specific version, you'd need to rebuild Python itself or use environment overrides like LD_LIBRARY_PATH : zlib1213tarxz

Even though you're compiling from source, ensure no residual system conflicts. Clean the build: make distclean
