Assume I have C++ app A and C++ libs B and C. A uses B and C, C uses B.
They all are in separate Git repositories and have the same compiler config in their CMakeLists.txt:
if ("${CMAKE_CXX_COMPILER_ID}" STREQUAL "Clang")
# using Clang
elseif ("${CMAKE_CXX_COMPILER_ID}" STREQUAL "GNU")
# using GCC
add_definitions("-Wall -Wextra -Wno-unused-function -pedantic -pthread")
elseif ("${CMAKE_CXX_COMPILER_ID}" STREQUAL "Intel")
# using Intel C++
elseif ("${CMAKE_CXX_COMPILER_ID}" STREQUAL "MSVC")
# using Visual Studio C++
add_compile_options("/Zc:__cplusplus")
add_compile_options("/W4")
add_definitions(-D_UNICODE)
add_definitions(-MP)
endif()
What is the right way to move this to a separate script and share it between A, B and C?
Should it be a CMake module?

I have a C/C++ project in which I want to use CppUTest.
So I include the dependency of CppUTest with:
include(FetchContent)
FetchContent_Declare(
CppUTest
GIT_REPOSITORY https://github.com/cpputest/cpputest.git
GIT_TAG latest-passing-build
CONFIGURE_COMMAND ""
BUILD_COMMAND ""
)
set(TESTS OFF CACHE BOOL "Switch off CppUTest Test build")
FetchContent_MakeAvailable(CppUTest)
This works fine.
In my (automotive) project, I use the C++20 standard and I need to enable all/most warnings. But when I do, CppUTest brings me a lot of warnings. So, I would like to compile CppUTest with different compiler options than the project's code.
How can I configure that in CMake?
I googled a lot but didn't find anything that works.
Thanks,
Stefan
PS: My simplified CMake file is:
cmake_minimum_required(VERSION 3.5)

### add tests
add_subdirectory(path/to/my/tests)
Do not use set(CMAKE_<LANG>*. Use *target* interfaces. If you do not want all stuff to be compiled with a specific option, do not set them globally. Instead:
set_target_properties(mytests PROPERTY
CXX_STANDARD 11
etc.
)
target_compile_options(mytests PUBLIC -option1 -option2 ...)
Anyway, SET(CMAKE_<LANG>_* affect targets declared after it. So move set(CMAKE_* after FetchContent_MakeAvailable(CppUTest)
I am trying to create a new macro in a Fortran file. Such file is one of many in a bigger project. It is compiled through a CMake file and gfortran.
For its simplicity I just included a simple example:
#define hello call
module SIO_ncDimBounds_mod
use SIO_ncParams_mod, only: MAX_DIMLEN_NAME
...
logical, parameter :: ISDEBUG = .false.
hello -> not recognized as Macro
When It is compiled it is ignored so it raises an error:
../soulio/src/ncDimBounds_mod.F90:34:2:
34 | hello
| 1
Error: Unclassifiable statement at (1)
As far as I understand, with upper case file extension should be enough to execute the preprocessor. I also checked the '-cpp' flag is enabled. I doubled checked with verbose mode to ensure it is enabled:

I did a simple and isolated test with a fortran file with an uppercase extension, as expected it works.
Why is the macro not replaced with CMake? It seems to me the preprocessor it is not called.
Edit:
'hello' is changed to lowercase
If we change the example to
subroutine silly()
print *, 'It works'
return
end subroutine silly
#define hello call
program main
hello silly
stop
end program main
and build using
gfortran -cpp macro.f90
This builds without any problems. If I just have hello on its own, then I get a syntax error.
First, make sure your program is valid. call on its own will generate an error. You need to call something.
Could you try building without cmake? If it works without cmake and doesn't work with cmake then it is a cmake problem. Otherwise, you just have a problem with your code.
When I build PCL library on Jetson TX2 from source via CMAKE, I get the following debug logs among other msgs:
-- CUDA NVCC target flags:
-gencode;arch=compute_30,code=sm_30;
-gencode;arch=compute_35,code=sm_35;
-gencode;arch=compute_50,code=sm_50;
-gencode;arch=compute_52,code=sm_52;
-gencode;arch=compute_53,code=sm_53;
-gencode;arch=compute_60,code=sm_60;
-gencode;arch=compute_61,code=sm_61;
-gencode;arch=compute_70,code=sm_70;
-gencode;arch=compute_72,code=sm_72;
-gencode;arch=compute_75,code=sm_75
This means the binary files generated will be 10 times heavier than compared to single SM architecture. Also the compilation takes 10 times longer. sm_62 doesn't need to be included because its the architecture of base machine.
I don't want the compatibility. How can I avoid generating these compatibilties?

I found a file which was causing the CMAKE to include 10 sm_arch in compatibility list. Here's the link. I will re-compile after editing the file for just 1 sm_arch and compare the size of binaries generated. – Anuj Patil Jan 22 at 18:10
So findCUDA was the culprit here. Editing the files to required sm_arch does the trick!
I'm trying to set a bunch of CXX flags based on processor type.
IF(${CMAKE_SYSTEM_PROCESSOR} STREQUAL "x86_64")
SET(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -DAMD64")
ELSE()
STRING(FIND ${CMAKE_SYSTEM_PROCESSOR} "86" 86_res)
IF(${86_res} EQUAL -1)
SET(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -DIA32")
ENDIF()
STRING(FIND ${CMAKE_SYSTEM_PROCESSOR} "arm" arm_res)
IF(${arm_res} EQUAL -1)
SET(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -DARM")
ENDIF()
ENDIF()
But for whatever reason CMAKE_SYSTEM_PROCESSOR is empty and can't run the STREQUAL comparison. Why is this empty?
For now I set this by running
EXEC_PROGRAM(uname ARGS -p OUTPUT_VARIABLE CMAKE_SYSTEM_PROCESSOR)
But that won't work on Windows so I'm not sure what I should do here.
The macro must be used AFTER setting the project name with PROJECT(...).
MESSAGE("CMAKE_SYSTEM_PROCESSOR: ${CMAKE_SYSTEM_PROCESSOR}") # EMPTY!
PROJECT(dummy)
MESSAGE("CMAKE_SYSTEM_PROCESSOR: ${CMAKE_SYSTEM_PROCESSOR}") # OK!
Output:

It could be assigned by toolchains when enabling cross-compiling.
There was once a bug related to cmake and pthread but it is now fixed.
I use cmake version 3.5.1 on Mac OS. It compiled previously but in the meantime I installed, changed, or updated things. I don't have much knowledge about cmake. The cmake file was written by someone else.
This is the error message I get:
-- Looking for pthread.h
-- Looking for pthread.h - not found

How do I fix this?
Thanks to #Tsyvarev.
The problem was that the "-fopenmp" flag was causing an error because the compiler was set to clang.
From the CMakeFiles/CMakeError.log
clang: error: unsupported option '-fopenmp'
Changing the C++ compiler to g++ and removing the flag from the c compiler solved the problem.
