Could you check the size of the executable which gets into the RPM
it should be located in:
<builddir>/_CPack_Packages/<packageName>/RPM/<packageFileName>/....
When CPackRPM runs you get a message like:
CPackRPM: Will use GENERATED spec file:
/blah/blah/.../RPM/SPECS/yourpackage.spec
then the directory to look into should be:
/blah/blah/.../RPM/<packageFileName>/
You can also extract the content of the generated RPM using rpm2cpio (or alien)
rpm2cpio <yourpackage>.rpm | cpio -idmv
alien -t <yourpackage>.rpm
tar zxvf <yourpackage>.tgz
then verify the size of the concerned file.

I bet you compare with a file produced by "make install/strip"?
a) The executable your are looking at may not be the same as the one
put into the RPM.
b) rpmbuild (which get called by CPackRPM) can post-process the
library/executable
depending on the distribution you are running on.
So first do the comparison with the package executable.
Then more questions:
1) On which kind of hosts do you create the RPM?
(Fedora Y, OpenSuSE W, Debian Z, etc...)
What is the version of RPM on this one:
rpm --version
2) On which king of target do you intsall it?
What is the version of RPM on the target:
rpm --version
In each case could check the dependency found in the RPM:
rpm -qp --requires yourPackage.rpm
> And how to fix it?
Depending on the discrepancy between the host and the target this may
not be fixable.
