I'm on Mac OS X, with the following CMake file, and Boost v1.58.0 installed at /usr/local/lib/boost_1_58_0, and every time I run cmake it prints "Could NOT find Boost". I've read through every stack overflow post I can about how to get this working, and nothing has worked. Is there something I'm just missing?

set (CMAKE_CXX_FLAGS "--std=gnu++11 ${CMAKE_C_FLAGS}")

if (Boost_FOUND)
include_directories (${Boost_INCLUDE_DIRS})
target_link_libraries (helloworld ${Boost_LIBRARIES})
endif ()
include_directories ("source")
add_executable (helloworld ${SOURCE_FILES})
This was breaking because optional isn't a library, it's header-only, so changing it to find_package (Boost 1.58.0) fixed the problem.

I am newbie on CMAKE. I am trying to make "fat executable file".
The term, fat executeable file, I mentioned, is a executable binary file which contains all shared libraries and can be just run in another environment.
Example (Trouble Situation)
There is ComputerA which is a computer that I used for developing. There is GCC, Boost libraries, librados etc.
And there is ComputerB which is a computer that I wanted to execute the binary that I built.
* Of course, Both Computer A and B have some conditions. Same Intel CPU Arch. (i7), Same CentOS.
I built binary file in ComputerA using CMAKE with this command, cmake .. && make. And I copied this file to ComputerB and executed.
When I execute the copied binary file in Computer B, it said like below.
[root#ComputerB ~]# ./binaryFile 123.123.123.123
./binaryFile: error while loading shared libraries: libboost_json.so.1.80.0: cannot open shared object file: No such file or directory
I understand what this error message say. There is no shared library which it needed. So, what I want to ask in this community is, What is CMAKE Command for containing shared libraries.
Similar thing :: fat JAR
The reason, why I called "fat executable file", is that there is a word "fat JAR" in Java. I am not familiar with Java. But it is commonly used word in Java community.
My CMAKE File
It contains some libraries like Boost, Rados, RBD etc. (There will be more according to progress of developing)

Find_package command is a nightmare to me.
I am trying to include some specified components in boost into my project.
Some components could not be found with find_package command for different error.
Can anyone help to explain the error reported?
case 1:
cmake_minimum_required(VERSION 3.15)
project(tryBoost)
set(CMAKE_CXX_STANDARD 14)
set(BOOST_ROOT "D:\\cygwin64\\home\\yubo\\boost_1_62_0") # either set it here or from the command line
find_package(Boost 1.62.0 REQUIRED COMPONENTS json) # header only libraries must not be added here
add_executable(tryBoost main.cpp)
I try to find json, but error reported：
No header defined for json; skipping header check
case 2:
cmake_minimum_required(VERSION 3.15)
project(tryBoost)
set(CMAKE_CXX_STANDARD 14)
set(BOOST_ROOT "D:\\cygwin64\\home\\yubo\\boost_1_62_0") # either set it here or from the command line
find_package(Boost 1.62.0 REQUIRED COMPONENTS system) # header only libraries must not be added here
add_executable(tryBoost main.cpp)
I try to find system, but error reported：
Could NOT find Boost (missing: Boost_INCLUDE_DIR system)
How boost organizes its components in sub dirs? How find_package command works when scaning boost root dir? why "header only libraries must not be added here".
thanks.

I have installed Intel opencl sdk for windows and opencl variable are added to the environment variables. I want to use this sdk with my Clion ide which I am unable to include it in my current project since it was CL/cl.hpp not found. How can add it to my project in Clion?

You need to provide information about include directory for OpenCL headers like you provided for Boost headers. Also, you need to link OpenCL libraries with your target.
In your CMakeLists...
For include and link directories:
link_directories(${Boost_LIBRARY_DIRS} ${OpenCL_LIBRARY})
include_directories(${Boost_INCLUDE_DIRS} ${OpenCL_INCLUDE_DIRS})
For linking libraries:
set(LIBS ${LIBS} ${Boost_LIBRARIES} ${OpenCL_LIBRARY})
I want to build the following project: https://github.com/reo7sp/tgbot-cpp
I get these errors: https://imgur.com/S9kgWyv
Makefile part 1: https://imgur.com/O222bJR
Makefile part 2: https://imgur.com/i68QLdC
Now, I think that I need zlib, openssl and boost. Curl seems to be optional.
What is "threads"?
And what is the difference between ...LIBRARY_DEBUG and ...LIBRARY_RELEASE?
What doe LIB and SSL mean in the gui? These "libraries" are not mentioned in the makefile?
I am desperate for days now. Please, help me.

It turned out that I needed to set some system variables for OpenSSL, ZLib, Boost, curl. For Zlib just do the same procedure. drescherjm was a huge help. So thanks!

Even though I have set BOOST_ROOT , it fails and gives the Boost Found False Message. What am I doing wrong here?
Edit: I have found that setting Boost_USE_STATIC_LIBS to OFF is resolving the issue. But I have to have it ON. What could be wrong here?
Your directory structure needs to look like this:
c:/boost/boost_1_55_0
and BOOST_ROOT is an environment variable set to c:/boost
I have found the reason why this code is not working. As I am giving value ON to Boost_USE_STATIC_LIBS, the result is that find_package will look for libboost_thread-vc100-mt-1_55 , which it will not find because building boost will give shared libraries as stated in this link. Refer to pic below:
