.dir-locals.el with emacs26

[olsen . carl]

Hi all,
I wonder if anyone can share some light on a problem that occurs to me while 
running emacs26.

The problem is that emacs26 seems to ignore my .dir-locals.el file.
When i run in emacs24 it works fine. 

Here is my .dir-locals.el


   ((nil
  (cmake-ide-cmake-opts . 
"-DCMAKE_TOOLCHAIN_FILE=/sysroots/x86_64-ocpsdk-linux/usr/share/cmake/OEToolchainConfig.cmake
 -DCMAKE_INSTALL_PREFIX=/home/ocp/user_sysroots/3.6.4/usr 
-DCMAKE_EXPORT_COMPILE_COMMANDS=1")
  (cmake-ide-build-dir . "/home/me/git/crypto/build")))


Thanks
