[英]find_package(Boost) returns empty Boost_LIBRARIES
cmake version 3.8.2 cmake版本3.8.2
I have a strange problem. 我有一个奇怪的问题。 When I do
find_package(Boost)
, then the Boost_LIBRARIES is empty. 当我执行
find_package(Boost)
,Boost_LIBRARIES为空。 But when I do find_package(Boost REQUIRED filesystem)
, the Boost_LIBRARIES variable shows the corresponding libraries. 但是当我执行
find_package(Boost REQUIRED filesystem)
,Boost_LIBRARIES变量显示相应的库。
In both the cases, Boost is found, because it shows that the Boost version is 1.64. 在这两种情况下,都找到了Boost,因为它表明Boost版本是1.64。
with REQUIRED 需要
-- Boost version: 1.64.0
-- Found the following Boost libraries:
-- filesystem
-- system
Boost_INCLUDE_DIRS: /usr/local/include
OpenCV_INCLUDE_DIRS: /usr/local/include;/usr/local/include/opencv
Boost_LIBRARIES: /usr/local/lib/libboost_filesystem.so;/usr/local/lib/libboost_system.so
OpenCV_LIBRARIES: opencv_calib3d;opencv_core;opencv_features2d;opencv_flann;opencv_highgui;opencv_imgcodecs;opencv_imgproc;opencv_ml;opencv_objdetect;opencv_photo;opencv_shape;opencv_stitching;opencv_superres;opencv_video;opencv_videoio;opencv_videostab
Without REQUIRED 没有要求
-- Boost version: 1.64.0
Boost_INCLUDE_DIRS: /usr/local/include
OpenCV_INCLUDE_DIRS: /usr/local/include;/usr/local/include/opencv
Boost_LIBRARIES:
OpenCV_LIBRARIES: opencv_calib3d;opencv_core;opencv_features2d;opencv_flann;opencv_highgui;opencv_imgcodecs;opencv_imgproc;opencv_ml;opencv_objdetect;opencv_photo;opencv_shape;opencv_stitching;opencv_superres;opencv_video;opencv_videoio;opencv_videostab
Shouldnt the boost libraries, also show just the libraries and not the whole path, like the opencv? 不应该是boost库,也只显示库而不是整个路径,比如opencv?
Although I have the program_options in the same folder, the Boost cannot find it and cmake throws an error. 虽然我在同一个文件夹中有program_options,但Boost无法找到它并且cmake会抛出错误。
Could not find the following Boost libraries:
boost_program_options
Please see the ll. 请看ll。
truncated ll output.....
-rw-r--r-- 1 root root 1558464 Aug 12 06:23 /usr/local/lib/libboost_program_options.a

No matter REQUIRED is present or not, it's always empty. 无论是否存在,它总是空的。

It seems a bug of FindBoost.cmake 这似乎是FindBoost.cmake的一个错误
