Could you provide more information on your systems? Linux distribution, CMake version, Java version (JDK/JRE) etc.

[randomxsk8]

Solved.
I installed last jdk9 from oracle instead openjdk and it works.
I got linux mint and i follow this guide for installing oracle jdk.. i hope that could be helpfull:

The Java detection on CMake's side may be improvable, but it is difficult to do that without the same system, and without breaking it for other people. The whole search can be improved by providing JAVA_HOME explicitly.

I am running into this same issue with Java detection. Sorry bit of a noob here, this is the error message

CMake Warning (dev) at /usr/share/cmake-3.18/Modules/FindPackageHandleStandardArgs.cmake:273 (message):
The package name passed to find_package_handle_standard_args (JNI) does
not match the name of the calling package (JNI2). This can lead to
problems in calling code that expects find_package result variables
(e.g., _FOUND) to follow a certain pattern.

Is there a reliable way to get around this? Running 5.8.10-arch -1
