[CMake] cmake and lincurl woes -help

[lux-integ]

Greeetings,

I have a computer with these:
--OS cblfs 64-bit-linux (3.10.6) amd64
--curl -70.30.0, cmake-2.8.11, openldap-2.4.35

I notice each tme I call /usrlocal//bin/cmake in a shell 

I end up with lines like these :-

/usr/local/bin/cmake: /usr/local/lib/libldap-2.4.so.2: no version information 
available (required by /usr/lib/libcurl.so.4)
/usr/local/bin/cmake: /usr/local/lib/liblber-2.4.so.2: no version information 
available (required by /usr/lib/libcurl.so.4)

though the cmake build  goes to completion.

I recently tried building poppler-2.24.0.  As far as I know openldap is not a 
depenfency of poppler but poppler failed to compile ending like  so:-

I would be grateful   for some advice

a) whether to upgrade to a new version of cmake or curl or both and if so 
whether to yank out the old version(s) beforehand or just install over.

Thanks in advnance
