Adding boost to existing cmake project fails

[MasterBe]

Hello,

I am having an issue using boost, I get the error: "fatal error C1083: Cannot open include file: 'boost/algorithm/string.hpp': No such file or directory". I got here following the steps:

1. git clone --recursive https://github.com/boostorg/boost.git
2. bootstrap and then .\b2
3. added boost includes and linked the libs in cmake lists as below:
   target_include_directories(${PROJECT_NAME} INTERFACE external/boost/libs/algorithm/include)
   target_link_directories(${PROJECT_NAME} INTERFACE external/boost/libs)
4. Then trying to use the boost string algos: #include <boost/algorithm/string.hpp>

Could you please help?

Thanks for reading!

I tried using vcpkg and did the below in Cmakelists:

Find and include Boost

find_package(Boost REQUIRED)
message(STATUS "Boost_INCLUDE_DIRS: ${Boost_INCLUDE_DIRS}")
message(STATUS "Boost_LIBRARIES: ${Boost_LIBRARIES}")

Include Boost headers

target_include_directories(${PROJECT_NAME} INTERFACE ${Boost_INCLUDE_DIRS})

Link against Boost

target_link_libraries(${PROJECT_NAME} INTERFACE Boost::headers)
still I get the same issue: fatal error C1083: Cannot open include file: 'boost/algorithm/string.hpp': No such file or directory
I am pretty sure I checked the include path and looked correct. Could please someone help?
