up dating linker ld on Mac - cmake

I am trying to compile an example pytroch c++ project using instructions at:
https://pytorch.org/cppdocs/installing.html
When i reach the point of calling:
cmake -DCMAKE_PREFIX_PATH=/absolute/path/to/libtorch ..
cmake --build . --config Release
I get an error:
ld: unknown option: --no-as-needed
clang: error: linker command failed with exit code 1 (use -v to see invocation)
make[2]: *** [BLOCK_READER] Error 1
make[1]: *** [CMakeFiles/BLOCK_READER.dir/all] Error 2
make: *** [all] Error 2
It looks like the issue is that the linker doesnt understand the option --no-as-needed.
After some research it looks like newer version of the linker support this option, but not the version i have.
So my question is how do i update my linker to a version that support this option?
I am on a Apple M1 (BigSur)..
It is my understanding that ld is part of gcc so can i just update gcc?
Btw here is my cmake CMakeLists.txt
cmake_minimum_required(VERSION 3.0 FATAL_ERROR)
project(block_reader)
# Setup Torch
set(CMAKE_CXX_COMPILER "/usr/bin/g++" CACHE STRING "C++ compiler" FORCE)

find_package(Torch REQUIRED)
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} ${TORCH_CXX_FLAGS}")
# Setup Torch
add_executable(BLOCK_READER main.cpp)
target_include_directories(BLOCK_READER PRIVATE /src)

Include tensorflow lite libraries in CMakeLists.txt of C++ project giving errors "undefined reference to `ruy::ScopedSuppressDenormals"

I'm trying to include TensorFlow lite libraries in CMakeLists.txt of C++ project. I followed the instructure in https://www.tensorflow.org/lite/guide/build_cmake
git clone https://github.com/tensorflow/tensorflow.git tensorflow_src
mkdir tflite_build && cd tflite_build
cmake ../tensorflow_src/tensorflow/lite -DTFLITE_ENABLE_XNNPACK=OFF
-DTFLITE_ENABLE_EXTERNAL_DELEGATE=OFF TFLITE_ENABLE_RUY=ON/OFF (tried both option)
cmake --build . --config release -j24
and added all the libs to the CmakeLists.txt file as follow

I don't want to add the libs as "add_subdirectory" as it was given in the guide because it will compile every time I create a new project
So how can I solve the undefined reference to `ruy::ScopedSuppressDenormals::ScopedSuppressDenormals()'
UPDATE:
if I change the CMakeLists.txt to :
cmake_minimum_required(VERSION 3.0.0)
project(main)
set(TENSORFLOW_SRC_DIR "test_cpp/tensorflow_src")

I take this error

I found this repo that contains all needed libs for the project https://github.com/muhammedakyuzlu/tflite-cpp-package
I believe that the problem you have is the ordering of the libs.
Try putting the libtensorflow-lite.a before the ruy-*.a in your setup.
There is another trick that could help you getting started.
Just add this to your CMake File:
include(FetchContent)
FetchContent_Declare(
tensorflow
GIT_REPOSITORY https://github.com/tensorflow/tensorflow.git
GIT_PROGRESS TRUE
GIT_SHALLOW TRUE
GIT_TAG v2.10.0
SOURCE_SUBDIR tensorflow/lite
)
FetchContent_MakeAvailable(tensorflow)
and link to the library:
target_link_libraries(${PROJECT_NAME} PRIVATE
tensorflow-lite
)
This is downloading all dependencies automatically and should make you ready to go.

How to add Ziplib library in Clion on Ubuntu

I'm trying to add ZipLip into my project using Clion on ubuntu, but I have this output:

Can someone help me to solve this please?
My ZipLib folder is in the same folder as my cmakefile.txt file.
The call to link_libraries() appears to accept the wrong arguments in this case. The link_libraries() command takes arguments of existing CMake targets, or library names. It is also redundant with your target_link_libraries() call, as this already links ZipLib to TryZip.
Try removing the call to link_libraries(), as this CMake function is deprecated and its use is highly discouraged. The include_directories() call is similarly deprecated, in favor of the target-specific command, so consider using target_include_directories() instead.
Assuming your added sub-directory ExternalLibrary/ZipLib contains an additional CMakeLists.txt file for configuring the ZipLib target, you should not need to add the ZipFile.cpp file again. If this file is already compiled in the sub-directory into the target ZipLib, you do not need to compile it again into TryZip.
add_subdirectory(ExternalLibrary/ZipLib)
set(CMAKE_CXX_STANDARD 17)
add_executable(TryZip main.cpp)
target_include_directories(TryZip PRIVATE ExternalLibrary/ZipLib)
target_link_libraries(TryZip PRIVATE ZipLib)
EDIT: Based on your feedback, it appears ZipLib also depends on pthread but somehow it is not getting linked correctly. You might try to add the following to your ExternalLibrary/ZipLib/CMakeLists.txt file (if it doesn't already exist), to utilize CMake's FindThreads module:
find_package(Threads REQUIRED)
...
target_link_libraries(ZipLib PUBLIC Threads::Threads)

How to link ICU4C in cmake via pkg-config on MacOS? [duplicate]

This question already has answers here:
Cmake cannot find library using "link_directories"
(4 answers)
Closed 3 years ago.
I work on macbook with newest OS. Installed icu4c library via homebrew. But I cannot link libicuuc correctly. In case of find library, I use
export PKG_CONFIG_PATH=$PKG_CONFIG_PATH:/usr/local/Cellar/icu4c/64.2/lib/pkgconfig
on my ~/.bashrc, but still got link error.
This is a very simple CMakeLists.txt:
cmake_minimum_required(VERSION 3.4)
project(xeditd CXX)
find_package(PkgConfig REQUIRED)
pkg_search_module(ICU_UC icu-uc)
set(LIB_DIR
${ICU_UC_LIBRARY_DIRS}
)
set(LIB
${ICU_UC_LIBRARIES}
)
set(INC_DIR
${ICU_UC_INCLUDE_DIRS}
)
set(SRC_FILE
xeditd.cpp
)
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++14 -o2 ${ICU_UC_CXXFLAGS_OTHER}")
message(${LIB_DIR})
message(${LIB})
message(${INC_DIR})
message(${CMAKE_CXX_FLAGS})
add_executable(xeditd ${SRC_FILE})
link_directories(${LIB_DIR})
target_link_libraries(xeditd ${LIB})
target_include_directories(xeditd PUBLIC ${INC_DIR})
It generate:

icuucicudata (${LIB})

I don't known why libicuuc.dylib not found.
link_directories only affects targets that come AFTER it. So I move add_executable after the link_directories call.

cmake on windows. Link libraries in folder

Disclaimer: I'm new to cmake so i have no idea what I'm doing.
All guides and tutorials i find seem to think I'm running a 20 man team that needs to work together.
All I'm trying to do is put all my libraries in an include folder and lib folder.
In visual studio and code::blocks i just set up the linker in the IDE, but cmake is a little hard for me to wrap my head around.
I've set include and link directories with
include_directories(${PROJECT_SOURCE_DIR}/include)
link_directories(${PROJECT_SOURCE_DIR}/lib)
Then i try to
target_link_libraries(${PROJECT_NAME} jsoncpp)
This however produces undefined references. Is there a simple way to add and link libraries without me having to google and add a cmake module for each one?
Edit:
attempts:
target_link_libraries(${PROJECT_NAME} libjsoncpp.a)
error: undefined reference
target_link_libraries(${PROJECT_NAME} libjsoncpp)
error: cannot find -llibjsoncpp
