试了下编译，linux说明文件里有几个变量名貌似有问题

[sq3536]

前面老不成功，折腾了挺久
PYTHON3_EXCUTABLE 少了个E 应该是PYTHON3_EXECUTABLE
PYTHON3_INCLUDE_DIR 貌似应该是 PYTHON3_INCLUDE_PATH
PYTHON3_LIBRARY 改成了 PYTHON3_LIBRARIES
PYTHON_NUMPY_PATH 改成了 PYTHON3_NUMPY_INCLUDE_DIRS 然后要到 /numpy/core/include这一级

另外贴一下调整后的 conda虚拟环境的

cmake -D CMAKE_BUILD_TYPE=RELEASE \
-D CMAKE_INSTALL_PREFIX=~/miniconda3/envs/[虚拟环境名称] \
-D BUILD_opencv_python2=OFF \
-D BUILD_opencv_python3=ON \
-D PYTHON3_EXECUTABLE=~/miniconda3/envs/[虚拟环境名称]/bin/python3.6 \
-D PYTHON3_INCLUDE_PATH=~/miniconda3/envs/[虚拟环境名称]/include/python3.6m \
-D PYTHON3_LIBRARIES=~/miniconda3/envs/[虚拟环境名称]/lib/libpython3.6m.so \
-D PYTHON3_NUMPY_INCLUDE_DIRS=~/miniconda3/envs/[虚拟环境名称]/lib/python3.6/site-packages/numpy/core/include .. \
&& make -j2 && sudo make install

The variable names seem vary in different tutorials.
For a reference of the names, please check:

On centos 7, the following setting is ok.
cmake -D CMAKE_BUILD_TYPE=RELEASE
-D BUILD_opencv_python2=OFF
-D BUILD_opencv_python3=ON
-D PYTHON_DEFAULT_EXECUTABLE=$(python -c "import sys; print(sys.executable)")
-D PYTHON3_EXECUTABLE=$(python -c "import sys; print(sys.executable)")
-D PYTHON3_NUMPY_INCLUDE_DIRS=$(python -c "import numpy; print (numpy.get_include())")
-D PYTHON3_PACKAGES_PATH=$(python -c "from distutils.sysconfig import get_python_lib; print(get_python_lib())") ..
&& make -j2 && sudo make install

你好虚拟环境路径按照你所说明的改了， 但是仍然报错

缺少.cmake那什么文件， 能看看么
