Can't link gegl libary with cmake

Question

I got the error message: :-1: Fehler: error: gegl-0.4: linker input file not found: No such file or directory:-1: Fehler: error: babl-01: linker input file not found: No such file or directory

So the linker cant find the libaries or can't link them for unknown reason.

I have tried:

cmake_minimum_required(VERSION 3.5)

project(perspective_lines LANGUAGES C)

set(CMAKE_C_FLAGS "${CMAKE_C_FLAGS} -lm gegl-0.4 babl-01 ")


#export (PKG_CONFIG_PATH="${GIMP_PREFIX}/share/pkgconfig:${GIMP_PREFIX}/lib64/pkgconfig${PKG_CONFIG_PATH:+:$PKG_CONFIG_PATH}"")

#add_compile_options(  -L/usr/lib64/libm.so -lm -std=gnu11 -v)

set(CMAKE_C_IMPLICIT_LINK_DIRECTORIES "/usr/lib64/gcc/x86_64-suse-linux/9;/usr/lib64;/lib64;/usr/x86_64-suse-linux/lib")

set(SOURCES  perspective_lines.c )

add_executable(perspective_lines perspective_lines.c)

target_link_libraries(perspective_lines "/usr/lib64/libbabl-0.1.so")
target_link_libraries(perspective_lines "/usr/lib64/libgegl-04.so")
#target_link_libraries(perspective_lines gegl)

install(TARGETS perspective_lines DESTINATION ~/.config/GIMP/2.10/plug-ins/)

This doesn't work also: set(CMAKE_C_FLAGS "${CMAKE_C_FLAGS} -lm gegl-0.4 -L /usr/lib64/libgegl-04.so")

Where is my mistake?

Thank you very much for your answer. That was the problem and... (its embarrassing) a wrong filename: target_link_libraries(perspective_lines "/usr/lib64/libgegl-0.4.so")
