change cmakelists.txt

SET(APPLE_LIBS ${APPLE_LIBS} ${GLFW3_LIBRARY} ${ASSIMP_LIBRARY} ${FREETYPE_LIBRARIES})

@hu5980 if you have a chance, please try compiling the branch of PR #215 and please report the results, good or bad. Since I don't have access to Mac OS, I can't test the effect of this PR. Thank you in advance.

I have tested it failed. My environmment is Mac OS 10.14.6 on HacMac

After I added freetype to CMakeLists.txt and installed freetype, the same compiled error is still there.

[rbarkmore]

@tainzhi can you please post the error messages? Thanks.

[upupming]

Also, make sure to add:

find_package(Freetype REQUIRED)

[tainzhi]

@upupming solution works. Thanks very much.
@rbarkmore Thanks for your kind help, too

SET(APPLE_LIBS ${APPLE_LIBS} ${GLFW3_LIBRARY} ${ASSIMP_LIBRARY} ${FREETYPE_LIBRARIES})

my mac system version is 10.15.7, I added ${FREETYPE_LIBRARIES} this in CMakeList.txt, but the same error exists,what can I do?

[noobxiaohai]

Also, make sure to add:

find_package(Freetype REQUIRED)

@tainzhi @upupming
which line in CMakeList.txt do I need to add 'find_package(Freetype REQUIRED)'?

when I add find here

# find the required packages
find_package(GLM REQUIRED)
message(STATUS "GLM included at ${GLM_INCLUDE_DIR}")
find_package(GLFW3 REQUIRED)
message(STATUS "Found GLFW3 in ${GLFW3_INCLUDE_DIR}")
find_package(ASSIMP REQUIRED)
message(STATUS "Found ASSIMP in ${ASSIMP_INCLUDE_DIR}")
# find_package(SOIL REQUIRED)
# message(STATUS "Found SOIL in ${SOIL_INCLUDE_DIR}")
# find_package(GLEW REQUIRED)
# message(STATUS "Found GLEW in ${GLEW_INCLUDE_DIR}")
find_package(Freetype REQUIRED)

this error appeared when i do 'make ../.'

[tainzhi]

you should add find_package(Freetype REQUIRED) at the apple ifelse branch, just before the line SET(APPLE_LIBS ${APPLE_LIBS} ${GLFW3_LIBRARY} ${ASSIMP_LIBRARY} ${FREETYPE_LIBRARIES}), such as line 50.
