Thanks for testing!
Oops, I fixed the issue today, but forgot about updating the gist.

Even with the current version, rpmbuild could fail because of syntax issues in the spec file of libtpms.
I locally fixed that, an upstream PR is to-do.

I tried the following:

sudo mkdir -p /root/rpmbuild/SOURCES/
sudo cp libtpms_0.7.7.orig.tar.gz /root/rpmbuild/SOURCES/libtpms-0.7.7.tar.gz

But then I get:

error: bare words are no longer supported, please use "...":  production == debug

error:                                                        ^
error: /home/alban/programs/windows-vm/libtpms/dist/libtpms.spec:81: bad %if condition:  production == debug

So I had to patch like this:

--- a/dist/libtpms.spec
+++ b/dist/libtpms.spec
@@ -78,11 +78,11 @@ Libtpms header files and documentation.
 %define _with_openssl --with-openssl
 %endif
 
-%if %{build_type} == debug
+%if "%{build_type}" == "debug"
 %define _enable_debug --enable-debug
 %endif
 
-%if %{build_type} == debug
+%if "%{build_type}" == "debug"
 CFLAGS=-O0
 %endif
 ./autogen.sh \

Then, I got the error:

+ rpmbuild -ba ./dist/swtpm.spec
error: Bad source: /root/rpmbuild/SOURCES/swtpm-enter_c.tar.gz: No such file or directory

Right, I updated the gist again.
It is about replacing "enter_commit_here" with an actual version, like:

sed -i -e "s/enter_commit_here/0.5.2/" ./dist/swtpm.spec
