CLion not finding Boost headers

Windows build 18362
CLion 2019.1.2
Boost 1.67
Toolchain mingw-64

I'm trying to setup a simple project in Clion using Boost. The problem is when I include a boost header #include <boost/log/trivial.hpp>, CLion cannot find the header file.

My CMakeLists.txt:

cmake_minimum_required(VERSION 3.14)
project(BoostTest)

set(CMAKE_CXX_STANDARD 14)

add_executable(BoostTest main.cpp)

set(BOOST_ROOT "$ENV{HOMEPATH}/.local/share/boost")
set(Boost_ARCHITECTURE "-x64")
find_package(Boost REQUIRED COMPONENTS log)
message(STATUS "Boost_INCLUDE_DIR: ${Boost_INCLUDE_DIR}")
include_directories(${Boost_INCLUDE_DIR})
target_link_libraries(BoostTest ${Boost_LIBRARIES})

The output of CMake seems to indicate that everything is found correctly:

C:\Users\michael\AppData\Local\JetBrains\Toolbox\apps\CLion\ch-0\191.6707.69\bin\cmake\win\bin\cmake.exe -DCMAKE_BUILD_TYPE=Debug -G "CodeBlocks - MinGW Makefiles" C:\Users\michael\projects\sml\BoostTest

But still CLion cannot find the header file in the include statement. The header files are indeed present at the location specified in Boost_INCLUDE_DIR. I'm new to Windows and CLion , and I probably missing some really basic, but I cannot see it. Any clues?

I just tried doing this from Ubuntu, and no need for any hack to get this working.

find_package(Boost 1.40 COMPONENTS system filesystem program_options log REQUIRED) include_directories(${Boost_INCLUDE_DIRS})

Not sure it may help, but at least it works somewhere.

After getting this to work from the command line, I've come to the conclusion that is a CLion bug. If the include directory does not include the drive designation (i.e., C:/), CLion is not finding the header files.

Here is a CMakeLists.txt that works for CLion:

cmake_minimum_required(VERSION 3.14)
project(boost-test)

set(CMAKE_CXX_STANDARD 14)
add_executable(boost-test main.cpp)

set(Boost_USE_STATIC_LIBS   ON)
find_package(Boost REQUIRED COMPONENTS log)
if (Boost_FOUND)
    message(STATUS "Boost_INCLUDE_DIRS: ${Boost_INCLUDE_DIRS}")
    include_directories("C:${Boost_INCLUDE_DIRS}")
    target_link_libraries(boost-test ${Boost_LIBRARIES})
endif()

This same file works from the command line without the hacky C: added to the include_directories.

Note that even without the C:, CLion will build and run the code just fine. So the issue seems to be solely with finding the header files based on include_directories().
