I can successfully build java opencv shared library libopencv_java410.so on linux redhat 7 using the following command:

wget https://github.com/opencv/opencv/arch...
tar -xf 4.1.0.tar.gz
mv opencv-4.1.0 src

install=pwd/release/install
mkdir -p $install
mkdir -p $install/lib

cd src
mkdir build
cd build

../../cmake-3.11.4/cmake/bin/cmake -DBUILD_SHARED_LIBS=OFF \ -DCMAKE_BUILD_TYPE=RELEASE \ -DBUILD_EXAMPLES=OFF \ -DBUILD_TESTS=OFF \ -DBUILD_PERF_TESTS=off \ -DWITH_IPP=OFF \ -DBUILD_PNG=ON \ -DBUILD_JPEG=ON \ -DBUILD_TIFF=ON \ -DBUILD_WEBP=ON ..

make -jnproc

However, when another project tries to use libopencv_java410.so, the following error would be given:
Native binary 'libopencv_java410.so' depends on 'libopenblas.so.0', which cannot be located

I checked the output of cmake, the lines about openblas are:
-- Could not find OpenBLAS include. Turning OpenBLAS_FOUND off
-- Could not find OpenBLAS lib. Turning OpenBLAS_FOUND off

I am not using the deep learning features of opencv, so I don't think I need to install openblas. How can I get rid of this error? Thank you very much!

However, when another project tries to use libopencv_java410.so,

huh, wait, on another machine / os / environment ? your libopencv_java410.so might be non-portable.

you built it on a box where openblas is available (so it's using it), but run it on a box, where it is not so ?

Yes, this is exactly the situation, I have to build it in one environment and distribute the libopencv_java.so to other machines to use it. And the machine I used to build the .so has openblas installed, but the machines which are going to use it doesn't have openblas. I would like to know is it possible to change some flag to prevent cmake from finding openblas, so the .so file built from it would not require libopenblas.so.
