I'm stuck on what seems like a rather simple problem.
I've got this in my CMakeLists.txt
set(BOOST_INCLUDEDIR ${CMAKE_CURRENT_LIST_DIR}/boost_1_59_0)
set(Boost_DEBUG 1)
find_package(Boost 1.59.0 EXACT REQUIRED)
The boost_1_59_0 I'm pointing it to contains the Boost source straight from
the 1.59.0 release.
I've tried both CMake 3.3.1 and 3.4.1. When I run CMake, I get the "Unable
to find the Boost header files" error. Here's some of the debug output:
-- [ FindBoost.cmake:551 ] _boost_TEST_VERSIONS = 1.59.0;1.59
-- [ FindBoost.cmake:553 ] Boost_USE_MULTITHREADED = TRUE
-- [ FindBoost.cmake:555 ] Boost_USE_STATIC_LIBS =
-- [ FindBoost.cmake:557 ] Boost_USE_STATIC_RUNTIME =
-- [ FindBoost.cmake:559 ] Boost_ADDITIONAL_VERSIONS =
-- [ FindBoost.cmake:561 ] Boost_NO_SYSTEM_PATHS =
-- [ FindBoost.cmake:613 ] Declared as CMake or Environmental Variables:
-- [ FindBoost.cmake:615 ] BOOST_ROOT =
-- [ FindBoost.cmake:617 ] BOOST_INCLUDEDIR =
/home/user/thirdparty/boost_1_59_0
-- [ FindBoost.cmake:619 ] BOOST_LIBRARYDIR =
-- [ FindBoost.cmake:621 ] _boost_TEST_VERSIONS = 1.59.0;1.59
-- [ FindBoost.cmake:690 ] Include debugging info:
-- [ FindBoost.cmake:692 ] _boost_INCLUDE_SEARCH_DIRS =
/home/user/thirdparty/boost_1_59_0;PATHS;C:/boost/include;C:/boost;/sw/local/include
-- [ FindBoost.cmake:694 ] _boost_PATH_SUFFIXES =
boost-1_59_0;boost_1_59_0;boost/boost-1_59_0;boost/boost_1_59_0;boost-1_59;boost_1_59;boost/boost-1_59;boost/boost_1_59
So I see that the FindBoost module picked up my BOOST_INCLUDEDIR hint. I
looked at the source for the FindBoost module, and it comes down to:
find_path(NAMES boost/config.hpp ...).
The file exists exactly where CMake says it's looking.
$ ls -l /home/user/thirdparty/boost_1_59_0/boost/config.hpp
-r--r--r-- 1 user user 2188 Nov 30 16:20
/home/user/thirdparty/boost_1_59_0/boost/config.hpp
Yet CMake is still setting Boost_INCLUDE_DIR-NOTFOUND.
I have tried removing boost_1_59_0 from my BOOST_INCLUDEDIR hint (since I
saw that portion of the path in the suffixes, but it doesn't help). The
only way I am able to get CMake to locate the boost headers is to install
them into a global location like /usr/local/include (which I'd like to
avoid).
