Call with -nobuiltin will still pull in pre-compiled *.slpp and *.slpa (was: 'make install' fails)

Currently, 'make install' fails; it seems to not be able to find the generated pkg ?

It does seem to generate the packages:

```
make
#... all kinds of stuff
[ 98%] Building CXX object CMakeFiles/hellosureworld.dir/src/hellosureworld.cpp.o
[100%] Linking CXX executable dist/Release/surelog
Creating staging for precompiled packages
Creating OVM precompiled package...
Creating UVM precompiled package...
Packages created
make[3]: Leaving directory '/home/hzeller/src/Surelog/build'
# ...
```

But then this happens
```
sudo make install
# ...
Install the project...

```
This is what is in build/dist/Release

```
$ find build/dist/Release/
build/dist/Release/
build/dist/Release/hellosureworld
build/dist/Release/uhdm-test2

build/dist/Release/uhdm-test3
build/dist/Release/uhdm-dump
build/dist/Release/uhdm-listener
build/dist/Release/surelog
build/dist/Release/uhdm-test4
```

These are the only places where directories named `pkg/` exist:
```
$ find . -name "pkg"
./third_party/UVM/ovm-2.1.2/examples/basic_examples/pkg
./third_party/UVM/uvm-1.2/examples/simple/basic_examples/pkg
./third_party/UVM/uvm-1.1d/examples/simple/basic_examples/pkg
```

Reproduce the failure with make followed by sudo make install, then inspect cmake_install.cmake around the reference to build/dist/Release/pkg and the package-generation output shown in the issue. Confirm the expected package location and make install complete without the missing-directory error; also verify the -nobuiltin behavior described in the title.
