Dear Ren=E9,

Thanks for your suggestion. I will try it with cmake3.3

Meanwhile, I went to individual directories of ~/src/picongpu and compiled
individual modules cuda_memtest, mpiInfo etc. in that directory itself.

After that I commented the lines having add_subdirectory() function in
cuda_memtest and mpiInfo  module in the file
~/src/picongpu/src/piconpu/CMakeLists.text (line number 293 and 307)

Now, when I used

rm -fR ~/build && mkdir ~/build && cd ~/build
$PICSRC/configure ~/paramSets/case001
make -j install

It compiled and installed successfully. I am yet to test an example. 
This is an issue with cmake  new version as mentioned in the link I have
given in my previous email.

Regards,
Ajit

Dear Ajit,

thank you for providing use with the link. We need to test cmake 3.5 with
PIConGPU.
Could you please install cmake 3.3 till we fix the issue.

best,
